True.

Trent + Rebecca would be karma at work.

It's really difficult to say who could be a good "match" for the current Rebecca because she just has too many issues. She may be book smart and a talented attorney, but she literally knows nothing about life, something she herself admitted.

Yes, the writers are definitely skilled in making Josh look like the villain—at least for now.
Things to remember about Valencia:
1. She is vain and can be mean—she prefers brutal "honesty" as in her song "Women gotta stick together" Even Josh's friends don't like her.
2. She is also bossy and manipulative—she…

Josh assumed that Rebecca was still with Greg when he confessed his feelings for her on the hood of the car.

True, but I suspect that Greg knew he would've lost out to Josh even if he expressed his feelings to Rebecca. After all, Rebecca chose to leave the wedding with Josh, and she actually kissed him first on the hood of the car. Josh just assumed Greg and Rebecca were still together.

Josh will probably discover that Valencia was a walk in the park compared to hyperintense, neurotic Rebecca, who will undoubtedly want to know exactly how Josh feels about her.

Oh no. Nobody could handle Rebecca indefinitely. Josh could probably deal with her for most of season two though. And that might feel like an eternity for him.

Agreed. Josh actually has the personality and temperament to handle Rebecca, if he wanted to.

Greg dodged a bullet. I think the Grebecca shippers will realize that next season.

I think Rebecca would be afraid that Trent would tell Valencia/Josh the truth about his "relationship" with Rebecca.

Absolutely. Or some variant. And it would put Valencia back into the romantic mix for season 2.

Even if Greg was a good date at the wedding, he didn't stand a chance against Josh.

Why would V and R hate Josh?

I wonder what the fallout will be. It's possible that V regrets her decision to dump josh and wants to reconcile. That could create tension, especially if R gets pushy/nuts with Josh.

And Trent.
